Tears are reported to have welled up in Dr. Martin Luther King’s eyes when he heard President Lyndon Johnson utter the words “We Shall Overcome,” a reference to the Civil Rights movement’s rallying cry, 25 minutes into his Special Message to the Congress, The American Promise on March 15, 1965.

This speech, given in the wake of state-sponsored horrors inflicted on peaceful black protestors in Selma, Alabama, is one of the most powerful I’ve ever heard, one of LBJ’s best. I’ve listened to it many times and it always moves me to tears of admiration and gratitude for what President Johnson did for America, fighting for civil rights and voting rights.
